Rashes On Abdomen And Inner Arm. Taking Lidene Tab Half. Cause For Rashes?

It does not itch , however a couple of weeks prior to the rash my wrists and palms were itching like mad!!. My cholesteral levels are good but, my Gamma level was 143. I am having it repeated, but it is a worry as I had not been drinking alcohol. The only medication I had been regularly taking was !/2 tablet Lidene for sleeping. I have discontinued those prio to my next text. Worried
